Santa Monica is an iconic beach city with a split personality — oceanfront luxury, dense condo and apartment living, rent-controlled buildings, and busy commercial corridors. That mix creates construction work found almost nowhere else: high-end condo remodels next to rent-controlled apartment upgrades, historic buildings beside new development, and salt air wearing on everything near the water. Projects here also come with extra layers — HOA approvals, building management coordination, tight access, parking constraints — and they almost always cross trade lines. A condo kitchen remodel needs plumbing moves; an apartment building needs repipes; a retail space needs a full TI. One multi-trade contractor simplifies all of it.
Mars Construction Industries Corp is a multi-trade general contractor based in Orange, CA, operating with 30+ years of hands-on experience. We hold four CSLB licenses in-house — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC (CSLB #1138550). One accountable team handles your construction, plumbing, drain and sewer work, and HVAC under a single contract — and we’re experienced with the HOA and building-management coordination Santa Monica projects require.
Construction & Remodeling Services in Santa Monica, CA
Condo and apartment remodels are a major part of our Santa Monica work. We remodel kitchens and bathrooms in condos, townhomes, and apartments — working within HOA rules, building hours, elevator reservations, and common-area protection — with our C-36 plumbing license in-house so fixture relocations and supply-line upgrades stay inside one job. For older apartment buildings, we perform repipes, water heater replacements, and gas line work, addressing the infrastructure that aging buildings need before finishes fail.
Salt air is a constant factor near the coast. We install, replace, and repair HVAC systems, including equipment corroded by marine exposure, and we handle the exterior-adjacent work that coastal conditions demand. Our drain and sewer services — camera inspection, hydro jetting, trenchless repair — come with a 20-year warranty on sewer lining, valuable in a dense city where excavation disrupts everyone.
On the commercial side, we handle tenant improvement for the retail, restaurant, and office spaces along Santa Monica’s commercial corridors — build-outs and renovations that combine construction with plumbing and HVAC, all under one contract. We also build ADUs through our sister brand ADU Cities (100+ built in four years) where lot conditions allow, and we perform whole-home renovations for the city’s single-family neighborhoods.

Frequently Asked Questions
Do I need a licensed contractor for my project?
In California, any construction project totaling $1,000 or more in labor and materials must be performed by a licensed contractor. Verify any license on the CSLB website before hiring. Ours is CSLB #1138550 — A General Engineering, B General Building, C-36 Plumbing, and C-20 HVAC.
Can you work within my HOA’s rules?
Yes. We’re experienced with condo and apartment remodels: HOA approval paperwork, insurance certificates, restricted work hours, elevator scheduling, and common-area protection. Share your HOA’s requirements up front and we’ll plan around them.
How does your estimate process work?
We visit the property, walk through the project with you, and provide a written estimate. For multi-trade projects — remodel plus plumbing, TI plus HVAC — we scope everything at once under one number.
Which trades do you handle in-house?
General construction and remodeling, plumbing, drain and sewer, and HVAC, all under our own licenses. Electrical work is performed by qualified licensed electricians we bring in, since we do not hold the C-10 electrical classification.
Do you handle plumbing or sewer emergencies?
Yes. Our sister brand 911 Drain Lines provides 24/7 drain and plumbing emergency service at 714.746.7611.
